Utilizing present clinical scanners (Magnetic Resonance MR, Computed Tomography CT), various accessories (e.g. coils, cushions, phantoms, contrast agent injectors etc.) used during the scan are arranged - on the basis of knowledge and experience of the operator - in cuboids or similar devices. However, misplacement of the accessories leads to an undesirable delay in the scan. Also, some damage could be caused if the accessories are not kept in a proper way. Scan time, being increasingly expensive, needs intelligent placement methods for accessories within the scanner room. Mishandling of the coils could change the transmitter adjustments and lead to artifacts in images, for example. A new system consists of a multiple camera system with/without processor, active or passive markers and a projector attached with a laser pointer. The system makes use of change detection algorithms to observe the activity in the scanner room. The camera system records the frequency of use of every accessory in the scanner room and suggests the operator after a certain duration about a proper positioning of the objects. After a user-defined time interval, the system can suggest to the operator the repositioning of the accessories.
